Therapeutic effect of co-administered salvianolate and atorvastatin calcium on coronary heart disease patients with angina pectoris, and their blood lipid levels

Purpose: To investigate the clinical effect of combination of salvianolate and atorvastatin on blood lipids of coronary heart disease patients with angina pectoris (CHD-AP).Method: Patients with CHD-AP (n = 104) from January 2016 to January 2017 were randomly assigned to two groups: control group treated with atorvastatin (10 mg/day), and study group was administered atorvastatin (10 mg/day, oral) plus salvianolate (200 mg/day in 5 % glucose, iv). Palpitation, chest distress, improvement in myocardial ischemia, myocardial function, and hemodynamics were determined and used to assess treatment effectiveness in the two groups. Differences in blood lipid profiles were also investigated.Results: Improvement in palpitation, chest distress, myocardial ischemia and myocardial function in the study group were significantly higher than in the control group (p < 0.05). In the study group, total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and triacylglycerols (TGs) significantly decreased, relative to the control group (p < 0.05).Conclusion: Treatment of CHD-AP patients with combination of salvianolate and atorvastatin significantly ameliorates coronary heart disease and angina pectoris, and also reduces their blood lipid levels.Keywords: Salvianolate, Atorvastatin, Coronary heart disease, Angina pectoris, Blood lipid

Identification of apoptosis-related key genes and the associated regulation mechanism in thoracic aortic aneurysm

Abstract Background This study investigated the role of apoptosis-related genes in thoracic aortic aneurysms (TAA) and provided more insights into TAA's pathogenesis and molecular mechanisms. Material/methods Two gene expression datasets (GSE9106 and GSE26155) were retrieved from the Gene Expression Omnibus (GEO) database. Apoptosis-related genes were obtained from the KEGG apoptosis pathway (hsa04210). Differentially expressed apoptosis-related genes were identified by performing differential expression analysis using limma for TAA blood and tissue samples. GO and KEGG enrichment analysis of the differentially expressed apoptosis genes was performed using the Metascape web tool. The miRNA-mRNA regulatory network was reconstructed using the ENCORI and miRDB databases, and functional enrichment analysis was performed on the related miRNAs using the miEAA tool. The correlation between the expression levels of differentially expressed apoptosis-related genes and genes involved in immune infiltration in TAA was calculated using the CIBERSORT algorithm. The apoptosis modification patterns mediated by differentially expressed apoptosis-related genes were systematically assessed in TAA samples. Results A total of 9 differentially-expressed apoptosis-related genes were identified in TAA samples compared with normal samples. 150 miRNAs and 6 mRNAs regulatory networks were reconstructed using the ENCORI and miRDB databases. Immune infiltration analysis revealed that the GZMB had the strongest positive correlation with activated NK cells and the DFFA presented the strongest positive correlation with T cells follicular helper. 3 distinct apoptosis modification patterns mediated by 9 differentially-expressed apoptosis-related genes were identified. They differ in immune characteristics and drug sensitivity, and their biological functions in these subtypes were further studied. Conclusions This study identified key apoptosis-related genes related to TAA and evaluated the modification patterns of key apoptosis genes in TAA, providing insights into potential targets and mechanisms of TAA pathogenesis and progression
